Transient Ischemic Attack l: Introduction

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Ischemic Stroke ll: Pathophysiology

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Area of Science:

Neurology
Neuroscience
Clinical Medicine

Background:

Paramedian caudal pontine infarctions commonly impact the medial lemniscus.
Medial lemniscus lesions typically result in dissociated sensory symptoms.

Purpose of the Study:

To report a case of bilateral caudal pontine infarction.
To describe the resulting sensory disorder in a patient's hands and distal arms.

Main Methods:

Case report presentation.
Clinical examination and neurological assessment.

Main Results:

The patient presented with a bilateral caudal pontine infarction.
A marked bilateral sensory disorder affecting the hands and distal arms was observed.

Conclusions:

Bilateral caudal pontine infarctions can lead to severe, bilateral sensory disturbances.
The medial lemniscus pathway is crucial for hand and arm sensation, and its bilateral damage can cause profound deficits.
